Perhaps you should try some spelling variations:
dinh lam » dinh van, tinh lao
cau treo » cau theo, cau tren, cau triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve pham » vi pham, v pham, ve phan
va dinh » van dinh, va kinh, va tinh
cuu tre » cua tre, cau tren
sac ky » cac ky, sai ky

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach y) OR (sac ky)) nang xa hoi. hieu ve pham duc va dinh lam ((cuu tre) OR (cau treo))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach y) or (sac ky)) nang xa hoi. hieu ve pham duc va dinh lam ((cuu tre) OR (cau treo))~".
• Adding a wildcard symbol may retrieve word variants: toc ((sach y) or (sac ky)) nang xa hoi. hieu ve pham duc va dinh lam ((cuu tre) OR (cau treo))*.
